I take it you've solved the immediate problem by blocking those
addresses and are wondering how to prevent this from occurring in the
future. Maybe check_sender_mx_access could help with this particular bozo.
You're said you already use greylisting and RBLs before doing SAV, I
don't think there is much else to do. The various smtp_*_timeout
parameters aren't likely to help much here.
I wonder if it would help or even make any sense for anvil(8) to
limit outgoing smtp?
